Cobalt blue glass stemware

This piece of stemware features a striking cobalt blue bowl paired with a clear glass stem and circular foot. The bowl has an elongated, slightly flared tulip shape that transitions smoothly into a pinched lower section where it joins the clear, slender stem. The stem is faceted or paneled, leading down to a flat, clear circular base. Physically, the glass appears smooth and glossy, with rich coloration concentrated in the upper bowl portion. There are no readily visible maker's marks, signatures, or stamps observable in the current lighting and angle, meaning the identification rests entirely on the visual characteristics of form and color rather than a specific branded stamp. The overall aesthetic is consistent with mid-century to late 20th-century decorative glassware, often produced by various European or American glassworks. The item appears to be in generally good condition with no glaring chips or cracks visible in the photograph, though minor surface wear or microscopic imperfections cannot be ruled out without a physical inspection. The craftsmanship displays clean joints between the colored bowl and clear stem elements.

Based on what I can see in the photograph, this piece of stemware features a striking cobalt blue tulip bowl paired with a clear, faceted stem and circular foot, consistent with mid-century to late 20th-century decorative glassware. The craftsmanship displays clean joints, and the item appears to be in generally good condition with no glaring chips or cracks visible. However, I can't verify from a photo whether there are microscopic imperfections, internal flaws, or exact glass compositions, and I would need physical inspection to confirm the presence of any maker's marks or signatures that are not visible in the current lighting. The aesthetic suggests production by various European or American glassworks, though the attribution remains a working hypothesis rather than a confirmed identification. My value estimate assumes the item corresponds to typical decorative glassware of this type and era. General market demand for vintage colored glassware is steady among casual collectors, though individual pieces typically trade in modest ranges unless associated with a highly documented maker. If this piece were to turn out to be a reproduction, modern replica, or simply an unattributed decorative item in the style of mid-century glassware, the value would likely decrease to the $10-$20 range. To establish a more precise evaluation and assess authenticity, an in-person examination by a glass specialist or physical inspection for hallmark and signature verification would be necessary.
